Technical Abstract

Multi-channel headphones capable of providing quality 3-dimensional (3-D) sound in an atmosphere of intimacy and privacy for individuals is provided. The multi-channel headphones ensure high-quality 3-D sound reproduction with accurate phase using distinct speaker units for multiple channels. The multi-channel headphones includes at least two speaker units for each ear piece, each for generating distinct sounds from multiple channels; and at least two enclosures in each of which each of the at least two speaker units arc installed. The multi-channel headphones include a sound guide portion in each of the enclosures to guide the sound emanating from the corresponding speaker unit into the listener's ear. A diffraction effect of the sound from the rear speaker can be induced. The multi-channel headphones can reproduce 3-D sound with the distinctness, spatial character caused by wide sound field, and directional phantom image, by arranging two speaker units for each ear piece in the front and rear directions around the listener's ear. Themultichannel headphones can efficiently reproduce sound from a 5.1 channel system, using only four speaker units.
